To all whom/t may concern.'

Be it known that l, CHARLEs HAMMER, a citizen of the- United States, and' a resident of Queens, in the county of Queens and State of New York, have invented certainnew and useful Improvements in Bandliu'g Closures, of which the following is a specification.

l This invention-relates to closures for glass containers, the object thereof being to provide an improved combined removable seal- .ing band and a rotatable and reusable closure.

@ne of the objects of the inventionis the provision of a shallow flanged cap having a plurality of projections adapted to engage the projections or threads of aglass eontainer and a removable sealing bandl cooperating with the cap in s\uch way as to materially extend below the flange thereof and engage directly with 'a shoulder of the container whereby the cap is securely retained on the `container and the'package effectively sealed, yet when the sealing band is'renioved the cap is reusable .on the rotation thereof to seal the container during the further use of the contents thereof,

Another object of the invention is .the pro-` vision of an improved glass containerhavingn special form of multiple threads or projections and ajspacedshoulder therebelow whereby a combined shallow flanged cap and sealing band maygb'e effectively used therewith so that the container maybe readif ly' sealed and the vcap reused upon the ree movalof the'band, and in which the cap and band can be sealed under considerable downward pressure without-the cap projections engaging the .container shoulder.

`l'n the accompanying drawing illustrating one embodiment ofmy invention` Fig. Yl is a plan `view partially broken away.

Fig. 2 is a partial vertical section ofthe cap and band before sealing.

F 3 is a partial-section showing the Fig. 4L shows the use of thecap after sea-led package has been opened.

This improved closure comprises a 4metal cap 2 and a sealing band Bparticularly applicable tov a glass container such as a -l. The cap 2 comprises a top 5 ,having a the that the-inclination of the ltapered end at the right hand of each projection or thread of vthe glassI container is somewhat sharper than the inclination of the lower edge of the nrojection. Below the projections 8 is a'ib, shoulder or` flange l() that'preferably projects outwjardv further than do the lugs 8, as indicated in Fig. 2. This rib lO'is also located below -the projections 8'a. suiicient distance to permit the-.lugs 7 on Lthe cap to slide along the entire lower faces of the projections 8` on the container without being brought into engagement with the rib 10. Heretofore, this rib l0 has been arrangedin close proximity to'the jar lugs or threads,

and this would tend to cause a kind of bind` ing or wedging action `of the cap .lugs between the projections and ribson the eontainer. i

The band 3 has its upper edgelQ bent over the topof the cap 5, and its lower edge 13 adapted to bend inwardly against the lower wall of the rib l0.

This cap shown has a raw or straight edge that is pressed inwardly at four points to form the lugs?.

It will 'be `further observed that the proj jections 8 on the containeror jar do not overlap at their adjacent ends, but are spacedw apart or separated in a vertical direction. This will facilitate the application ofI the Tt will be further understood that the lugs on .the cap are-arrangedfrelative toy thein- -clined threads 8 sogthnt in the subsequent use the lugs will engage' the lower faces of each thread to draw the cap w1thits liner 14 practically cap, as the lugs 7 can pass freely down bedown onthe jar as indicated in Fig. 4..

Then-the cap is first applied the lug will be cap is put on andthe lug passedbetween the ends of the threads, and the cap seated on rtop of the jar. v

Thereupon the band 3 1s applied, so that its bent top edge l2 will engage the top 2 at the outer portion as indicated in Fig. 2. This will bring the lower portion 13 oftheband below the rib l0, and.

while pressure is still applied on the upper flange- 12 of' the band in a downward direction, the lowery portionl 13 is bent inwardly against the lower wall of the'rib 10, as.

shown in Fig. 3. 'This will cause avery stron and tight seal of the closure on the container. The band may have lapping endsy in the 'form of a tongue 15, that may have another tongue 16 projecting through a slot 1 the sealing band is of such depth or height] in the other tongue, that will hold the band together at the ends but permit easy removal by bending back the two tongues.

When it is desired to have access to the container, the band is loosened and removed and this will leave the lug closure free for removal. The lug cap can now be returned to the container if onlyl partially used, and can be reused a number of ytimes by simply screwing the lugs down lfirmly under the thread portions 8.

From the foregoing itwill be seengthat the skirt or flange of the cap is-of just sufiicient [height or depth to' overlap thethreads of the glass container so that the cap can he made with `a shallow flange or skirt while that it will overlap the shallow flange or skirt and will also extend beyond the samev and overlap the shoulder or rib on theglass y container and that furthermore the shallow flange is of just such depth as willJ enable its lugs to pass under the glass threads of the containerand effectively pass therebetweenand the shoulder or (rib on the container,

which latter projects sufficiently beyond the glass threads to enable the overlapping sealing band to engage the same on its outer wall and to be bent under the same in an effective )manner to hold the cap in place. Furthermore by reason of the space between the ends of the glass threa s the. cap can be efficiently pressed down wit out turning "it when the sealing band is applied andthis effective sealing is also obtained even though the cap may be somewhat turned' by reason of the sharp inclination at the ends of the threads on the container and seal such container by overlapping both the capand the jar below the shallow flange of the cap so that the band can be effectively turned under and engage the glass shoulder of the ar itself and I believe that I am the first to provide a combined. shallow flanged cap and sealing band of .substantially twice the height of the cap; in other words a combined rotatable can and sealing band which is effective to overlap the entire skirt of the cap and extend such distance therebeyond as to overlap also a portion of' the glass container and be secured by being bent so as to directly engage under the shoulder of such container. The construction also vpermits the use of a shallow flange cap which materially'results in -a saving of metal and also enables the use of a glass container having a neck of less height.

I also believe that I am the first to pro-l vide a sealed package in which the structure is such that vertical movement in one direction during the operation of sealing the band under the shoulder and without the necessity of rotating the cap `is permitted'. Aside from the other advantages hereinbefore .set

forth it will be seen that this improved packf age enables the user to readily determine whether the sealed package has been tampered with or not.

Moreover it will be observed that the sealing band andcap so cooperate that the sealing band forms the first or primary lockin f* I,provement is particularly well adapted for shallow ,flanged caps, it of course could bel 'used with skirts or flanges of greater depth vif found desirable, andftherefore it is to be understood thatfby ldescribing in detail here` in any]y particular form, structure or arrangement, it\is not intended to limit the invention beyond the terms of theseveral claims or the requirements of the prior art Vrlhat I claim is; I
